A year after launching a solo country career, the Aerosmith frontman is hitting the road this summer with a new band (the Nashville-based Loving Mary) and a different approach to playing live. On his 19-city Out on a Limb tour, kicking off July 2 in Las Vegas, the rock icon is trading arenas for more intimate concert venues, where he'll rework Aerosmith classics and tell stories behind some of the band's most beloved hits.
